Chunky Monkey Cupcake Recipe

This cupcake recipe brings together my love of chocolate and peanut butter with one of the staple foods in our home, bananas.

We live in a sub tropical climate and have  an over abundance of bananas. Some days the harvest is so bountiful that we are all kept quite busy drying them, freezing them, making banana smoothies, baking banana bread and most recently, creating the most amazing banana and raspberry icy poles.

 I read once that Elvis Presley was an enormous fan of the combination of banana and peanut butter. I have come across a few cupcake recipes that pay homage to the king of rock and decided to make up my own delicious version of these flavoursome Chunky Monkey cupcakes. They have quickly become a favourite and I hope you enjoy them. x
